The Energy Assistance Fund (EAF) is a voluntary, nonprofit fuel fund that provides grants to income qualified utility customers in an effort to help those customers avoid electricity service disconnection. The administering utility and the energy industry as a whole is undergoing transformative change, resulting in a projected decrease of fundraising capacity for EAF among its most substantial donor pool - utility shareholders and employees. Utility customers represent a small percentage of EAF donors, despite the significant size of the customer base. Through a series of ethnographic interviews and secondary research, this thesis seeks to understand the demographics and motivations of utility customers who donate to EAF in order to help improve EAF’s fundraising strategy and donor solicitations to eventually grow customer donations. The goal of EAF is to maintain or grow donations from 2014 levels so the Fund can continue to serve income qualified customers facing energy poverty. This thesis provides a contextual review of fuel funds; challenges faced by the energy and utility industry; the politics and culture of energy; as well as nonprofit sector fundraising challenges and cultures/motivations of giving. This thesis includes client deliverables such as thick description of donor motivation, motivation themes and a donor …

Beethoven's rich compositional language evokes unique problems that have fueled scholarly dialogue for many years. My analyses focus on two types of paradoxes as central compositional problems in some of Beethoven's symphonic pieces and piano sonatas. My readings of Beethoven's Piano Sonata No. 27 (Op. 90), Symphony No. 4 (Op. 60), and Symphony No. 8 (Op. 93) explore the nature and significance of paradoxical unresolved six-four chords and their impact on tonal structure. I consider formal-tonal paradoxes in Beethoven's Tempest Sonata (Op. 31, No. 2), Ninth Symphony (Op. 125), and Overture die Weihe des Hauses (Op. 124). Movements that evoke formal-tonal paradoxes retain the structural framework of a paradigmatic interrupted structure, but contain unique voice-leading features that superimpose an undivided structure on top of the "residual" interrupted structure. Carl Schachter's observations about "genuine double meaning" and his arguments about the interplay between design and tonal structure in "Either/Or" establish the foundation for my analytical approach to paradox. Timothy Jackson's reading of Brahms' "Immer leiser word meine Schlummer" (Op. 105, No. 2) and Stephen Slottow's "Von einem Kunstler: Shapes in the Clouds" both clarify the methodology employed here. My interpretation of paradox involves more than just a slight contradiction between two …

Adult educators are a growing part of American higher education. Because of their increasing prominence in adult education, it is essential to understand what roles these educators play and what motivates them to remain in the profession despite poor work prospects and conditions. Research to date, however, focuses primarily on the adult learner and not the adult educator. The purpose of this qualitative, multiple-case study was to explore the role and motivation for teaching of adult educators employed as adjunct faculty in an accelerated degree program at a small, liberal arts college in the northwest United States. Purposeful sampling was used to select the five participants for the study. All participants taught in the program for more than five years and were considered to be successful in their positions by peers, students, and administrators. The study employed a preliminary demographic survey to solicit initial background data on the instructors. Other data collection included in-depth, open-ended, face-to-face interviews, document analysis, and classroom observation. The results showed that all five participants identified the following roles and assumed them in the classroom: (a) facilitator, (b) listener, (c) specialist, (d) guide, (e) adviser, and (f) co-learner or colleague. Further results showed that all five …

Ethical codes and laws provide counselors with guidance for how to approach confidentiality, but there is a gap in the literature surrounding counselors' process of decision-making when managing confidentiality with adolescent clients. This study explored the decision-making process of master therapists concerning adolescent clients. I conducted semi-structured interviews with peer identified master therapist (N=10), all of whom were licensed professional counselors with 15 or more years of counseling experience and whose case load contained 25% or more adolescent clients. Participants included seven females and three males; nine participants identified as Caucasian, and one participant identified as Hispanic. Participants ages ranged from 39-61. I analyzed the data, along with two research partner, according to Grounded Theory (GT) methodology. Through constant comparative analysis, a grounded theory emerged from the data in which participants converged understanding of client safety, relationships, clinical intuition in a process of integrated experience and consultation. With the exception of mandated reported and mortal danger, ethical guidelines and laws did not seem to factor into participants' decision making. Implications for counseling practice, preparation, and research are provided.

As science and technology continue to advance, innovative developments in transportation can enhance product safety and security for the benefit and welfare of society. The federal government requires every commercial truck to be inspected before each trip. This pre-trip inspection ensures the safe mechanical condition of each vehicle before it is used. An Unmanned Aerial Vehicle (UAV) could be used to provide an automated inspection, thus reducing driver workload, inspection costs and time while increasing inspection accuracy. This thesis develops a primary component of the algorithm that is required to implement UAV pre-trip inspections for commercial trucks using an android-based application. Specifically, this thesis provides foundational work of providing stable height control in an outdoor environment using a laser sensor and an android flight control application that includes take-off, landing, throttle control, and real-time video transmission. The height algorithm developed is the core of this thesis project. Phantom 2 Vision+ uses a pressure sensor to calculate the altitude of the drone for height stabilization. However, these altitude readings do not provide the precision required for this project. Rather, the goal of autonomously controlling height with great precision necessitated the use of a laser rangefinder sensor in the development of the …

Since their emergence in the early 1990s, neonicotinoid use has increased exponentially to make them the world's most prevalent insecticides. Although there is considerable research concerning the lethality of neonicotinoids, their sub-lethal and developmental effects are still being explored, especially with regards to non-mammalian species. The goal of this research was to investigate the effects of the neonicotinoid imidacloprid on the morphological and physiological development of northern bobwhite quail (Colinus virginianus). Bobwhite eggs (n = 650) were injected with imidacloprid concentrations of 0 (sham), 10, 50, 100 and 150 grams per kilogram of egg mass, which was administered at day 0 (pre-incubation), 3, 6, 9, or 12 of growth. Embryos were dissected on day 19 when they were weighed, staged, and examined for any overt structural deformities. Embryonic heart, liver, lungs and kidneys were also weighed and preserved for future use. Treated embryos exhibited increased frequency of severely deformed beaks and legs, as well as larger hearts and smaller lungs at the higher dosing concentrations. Some impacts are more pronounced in specific dosing periods, implying that there may be critical windows of development when embryos are highly susceptible to neonicotinoid exposure. This investigation suggests that imidacloprid could play a significant …

The instructional practices of three current classroom teachers who formerly served as Servant Leader Interns (SLIs) in the Children’s Defense Fund Freedom Schools (CDFFS) Program were examined. Haskell (2001) outlined eleven principles of transfer of learning, which were used to survey the levels of transfer established from service in Freedom Schools to practice in the traditional classroom. Individual surveys, The Freedom School Pedagogies Teacher Observation Record (FSPTOR) along with interviews of each participant were used for data collection; all three components were used to triangulate the findings. The findings from this study verified that low transfer was observed when the minimal application of the principles of learning was applied. This study revealed that for transfer to occur at high levels, it is imperative that adherence to all 11 principals is made, and the understanding of transfer, the application of transfer, and reflection on transfer are implemented. If the transfer of instructional practices is a goal of CDFFS for SLIs, the CDFFS program should consider implementing transfer of learning theory in future SLI training.

This a/r/tographic dissertation offers opportunities to interrogate curator identity and curator ways of being in both public and private spaces. Instead of an authoritative or prescriptive look at the curatorial, this dissertation as catalogue allows for uncertainty, for messiness, for vulnerable spaces where readers are invited into an exhibition of disorderly living. Stitched throughout the study are stories of mothering and the difficulties that accompanied the extremely early birth of my daughter. Becoming a mother provoked my curating in unexpected ways and allowed me to reconsider the reasons I collect, display, and perform as a curator. It was through the actual curating of familial material artifacts in the exhibition Dress Stories, I was able to map the journey of my curatorial turns. My engagement with clothing in the inquiry was informed by the work of Sandra Weber and Claudia Mitchell, where dress as a methodology allows for spaces to consider autobiography, identity, and practice. It was not until the exhibition was over, I was able to discover new ways to thread caring, collecting, and cataloging ourselves as curators, artists, researchers, teachers, and mothers. It prompts curators and teachers to consider possibilities for failure, releasing excess, and uncaring as a way …

This study was aimed at determining whether the digital volume pulse waveform using the Pulse Sensor can be used to extract features related to arterial compliance. The Pulse Sensor, a low-cost photoplethysmograph, measures green light reflection in the finger and generates output, which is indicative of blood flow and can be read by the low-cost Arduino UNO™. The Pulse Sensor code was modified to increase the sampling frequency and to capture the data in a file, which is subsequently used for waveform analysis using programs written in the R system. Waveforms were obtained using the Pulse Sensor during two 30-s periods of seated rest, in each of 44 participants, who were between the ages of 20 and 80 years. For each cardiac cycle, the first four derivatives of the waveform were calculated and low-pass filtered by convolution before every differentiation step. The program was written to extract 19 features from the pulse waveform and its derivatives. These features were selected from those that have been reported to relate to the physiopathology of hemodynamics. Results indicate that subtle features of the pulse waveform can be calculated from the fourth derivative. Feature misidentification occurred in cases of saturation or low voltage and …

Organometallic catalysis has attracted significant interest from both industry and academia due to its wide applications in organic synthetic transformations. Example of such transformations include the reaction of a zinc carbenoid with olefins to form cyclopropanes. The first project is a computational study using both density functional and correlated wavefunction methods of the reaction between ethylene and model zinc carbenoid, nitrenoid and oxenoid complexes (L-Zn-E-X, E = CH2, NH or O, L = X = I or Cl). It was shown that cyclopropanation of ethylene with IZnCH2I and aziridination of ethylene with IZnNHI proceed via a single-step mechanism with an asynchronous transition state. The reaction barrier for the aziridination with IZnNHI is lower than that of cyclopropanation. Changing the leaving group of IZnNHI from I to Cl, changes the mechanism of the aziridination reaction to a two-step pathway. The calculation results from the epoxidation with IZnOI and ClZnOCl oxenoids suggest a two-step mechanism for both oxenoids. Another important example of organometallic catalysis is the formation of alkyl arenes from arenes and olefins using transition metal catalysis (olefin hydroarylation). We studied with DFT methods the mechanism of a novel Rh catalyst (FlDAB)Rh(TFA)(η2–C2H4) [FlDAB = N,N’ -bis(pentafluorophenyl)-2,3-dimethyl-1,4-diaza-1,3-butadiene; TFA = trifluoroacetate] that converts …

Staff training packages combining instructions, modeling, practice, and feedback have been shown to be effective in demonstrating skills to work in early intensive behavioral intervention, but maintenance and generalization of the skills trained are often not addressed. Establishing a community of practice, in which staff members continue to learn and develop new skill sets from one another through shared experiences and information, may lead to the endurance and maintenance of desired staff behavior over time. The purpose of the current study is to evaluate the effects of a behaviorally designed community of practice on staff use of socially embedded consequences. The effects of the training procedure were evaluated using a concurrent multiple baseline design across two sites (7 staff members). The results suggest that the behaviorally planned community of practice was effective in reinforcing and maintaining staff use of socially embedded consequences for at least 5 to 9 weeks. Additionally, the number of learning opportunities provided by the staff and social engagement between staff and child increased.

Bombarded by constant and rapid change, healthcare organizations feel a sense of urgency to meet their needs for leaders. They rely on physicians to lead at all levels in their healthcare organizations. For them to successfully navigate today's healthcare environment, they require more than a medical education. To address this need, healthcare organizations are developing in-house leadership development programs.In this paper, I conduct a case study of physicians transitioning into leadership and their self-efficacy facilitated through an in-house leadership development program. Documentation, semi-structured interviews, and observations are examined to explore how physicians think about their leadership experiences following their participation in a six-month leadership development program.The study also explores at a high-level how these experiences influenced physician's self-efficacy as a first step in developing a theory of physician leadership and self-efficacy.

Wonder has had a rich and diverse history in the western philosophical tradition. Both Plato and Aristotle claim that philosophy begins in wonder, while Descartes marks it as the first of the passions and Heidegger uses it as a signpost for a new trajectory of philosophy away from idealism and nihilism. Despite such a rich history, wonder is almost always thought to be exhausted by the acquisition of knowledge. That is, wonder is thought of almost exclusively in epistemological terms and is discarded as soon as knowledge has been achieved. In this dissertation, I argue for an ontological reorientation of wonder that values wonder beyond its epistemic uses. To do this, I read the phenomenological and ontological work of Maurice Merleau-Ponty through recent developments in object-oriented ontology and new materialism. Much of Merleau-Ponty's work is directed toward dissolving the distinction between subject and object. His insights regarding the mutual constitution of the world lead to the possibility of an operative wonder that occurs between subject and object. Both object-oriented ontology and new materialism radicalize these insights by articulating them in terms of a vibrant or quasi-agential material world. Objects and assemblages of objects are capable of performing the becoming of …

The purpose of this research was to investigate the preferences of online students for technology-based learning environments (TBLEs) as influenced by the level of social presence in the online courses the participating students have taken. This investigation was centered around utilizing TBLEs and methods for establishing social presence in online classes (MESPOC) survey instruments to obtain the preferences of current online students at public university in the state of Texas. This study assumed a qualitative research structure comprising analysis of the data obtained on the TBLE and MESPOC instruments followed by semi-structured interviews with some of the survey participants. The results of the studies indicated that an individual’s preferred online learning environments impacted satisfaction in an online course. Moreover, the study, also explored the students’ preferences when it comes to the organization and facilitation of online courses.

The materials of war, defined as what soldiers carry into battle and off the battlefield, have much to offer as a means of identifying and analyzing the culture of those combatants. The Vietnam War is extremely rich in culture when considered against the changing political and social climate of the United States during the 1960s and 70s. Determining the meaning of the materials carried by Vietnam War soldiers can help identify why a soldier is fighting, what the soldier’s fears are, explain certain actions or inactions in a given situation, or describe the values and moral beliefs that governed that soldier’s conduct. “Carry,” as a word, often refers to something physical that can be seen, touched, smelled, or heard, but there is also the mental material, which does not exist in the physical space, that soldiers collect in their experiences prior to, during, and after battle. War changes the individual soldier, and by analyzing what he or she took (both physical and mental), attempts at self-preservation or defense mechanisms to harden the body and mind from the harsh realities of war are revealed. In the same respect, what the soldiers brought home is also a means of preservation; preserving those …

Two-dimensional (2D) transition metal dichalcogenides (TMDs) show great potential for the future electronics, optoelectronics and energy applications. But, the studies unveiling their interactions with the host substrates are sparse and limits their practical use for real device applications. We report the facile nano-scratch method to determine the adhesion energy of the wafer scale MoS2 atomic layers attached to the SiO2/Si and sapphire substrates. The practical adhesion energy of monolayer MoS2 on the SiO2/Si substrate is 7.78 J/m2. The practical adhesion energy was found to be an increasing function of the MoS2 thickness. Unlike SiO2/Si substrates, MoS2 films grown on the sapphire possess higher bonding energy, which is attributed to the defect-free growth and less number of grain boundaries, as well as less stress and strain stored at the interface owing to the similarity of Thermal Expansion Coefficient (TEC) between MoS2 films and sapphire substrate. Furthermore, we calculated the surface free energy of 2D MoS2 by the facile contact angle measurements and Neumann model fitting. A surface free energy ~85.3 mJ/m2 in few layers thick MoS2 manifests the hydrophilic nature of 2D MoS2. The high surface energy of MoS2 helps explain the good bonding strength at MoS2/substrate interface. This simple adhesion …

The purpose of the study was to examine district, campus, and community determinants of principal’s salaries using a spatial econometric framework. Among the district variables business tax (p = 0.001), property tax (p < .01), and the Herfindahl Index (measure of competition) were statistically significant indicators of principal salaries. The results suggest that more affluent districts tend to pay principals higher salaries, which was expected. Regarding campus characteristics, the percent of economically disadvantaged was not a statistically sound indicator (p = 0.468), but campus enrollment was significant (p = <.01). Interestingly as the percentage of economically disadvantaged students increased, the principal salary decreased. In contrast, as student enrollment increases the salary of principals increases, suggesting that principals of larger campuses earn higher salaries. Interestingly, student achievement was not a statistically significant predictor of principals’ salary given that pay for performance in Texas is at the forefront of political debate. Among the variables examined at the community level, only the percentage of homes owner occupied (p = 0.002) was found to be a statistically significant indicator of principal salary (p = .002). The lack of evidence on reforms, such as determinants of principal salary, points to data and research deficiencies to …

This dissertation explores the themes of collaboration and creativity in the relationship between arranger Nelson Riddle and vocalists Frank Sinatra and Ella Fitzgerald. It examines the balance between structure and freedom as well as the specific musical results that emerge from collaboration between an arranger and vocalists who are considered among the greatest in their fields. An examination of their interactions, musical scores, and performances, reveals that the constraints that are present in a collaborative effort can lead the artists to find a shared process to make a creative, unified product.

This study uses the storm surge sediment beds deposited by Hurricanes Audrey (1957), Carla (1961), Rita (2005) and Ike (2008) to investigate spatial and temporal changes in sedimentation rates on the McFaddin National Wildlife Refuge in Southeast Texas. Fourteen sediment cores were collected along a transect extending from 90 to 1230 meters inland from the Gulf Coast. Storm-surge-deposited sediment beds were identified by texture, organic content, carbonate content, the presence of marine microfossils, and Cesium-137 dating. The hurricane-derived sediment beds are marker horizons that facilitate assessment of marsh sedimentation rates from nearshore to inland locations as well as over decadal to annual timescales. Near the shore, on a Hurricane Ike washover fan, where hurricane-derived sedimentation has increased elevation by up to 0.68 m since 2005, there was no measurable marsh sedimentation in the period 2008-2014. Farther inland, at lower elevations, sedimentation for the period 2008-2014 averaged 0.36 cm per year. The reduction in sedimentation in the period 2008-2014 on the nearshore part of the marsh is likely due to reduced flooding in response to increased elevation from hurricane storm surge sediment deposition. These results provide valuable knowledge about the sedimentary response of coastal marshes subject to storm surge deposition and …

This paper explores various technologies available to the modern composer and utilized in recent modern opera, providing creative approaches to producing aural, visual, and theatrical performance environments. It also explores my own use of digital technology in Transient Delete. Transient Delete is a digital miniature-opera that explores different aspects of a community of post-human cyborgs. The story follows Iméra, a newly converted cyborg as she acclimates herself to this new cybernetic existence. During this process she meets several other cybernetic entities that are there to help guide her through her metamorphosis.

Representatives of the City of Highland Village expressed concern over the risk of wildfires for their community. Anthropology provides many tools for and examples of disaster assessment of preparedness, response, recovery, and mitigation. These tools combined with Geographic Information Systems (GIS) can provide a holistic, cultural ecological look at how such a disaster may take place in the city. The project's methods included a detailed survey of preparedness steps which was analyzed using SPSS and also imported into ArcGIS for spatial analysis, and semi-formal, in-depth interviews with residents of the community regarding preparedness, response, and recovery. Residents fell into a middle category of preparedness, with the majority of participants considering or implementing a few recommended preparedness steps. Interview participants expressed respect for and trust of the city and first-responders, as well as a willingness to volunteer their help during response and recovery stages. Finally the American Community Survey showed that resident socioeconomic vulnerability was considerably low, and no action needed to be taken to advocate for at-risk individuals. Overall, the City of Highland Village showed a high resiliency to disaster. A wildfire likely will not have a major impact on the community as a whole, though the city may reduce …

Circumscription and Compromise theory suggests self-concept and sex stereotype explain occupational preferences, including preferences for science, technology, engineering and mathematics (STEM). Support exists for sex differences between males and females in both science degrees and science careers. The main thrust of observed sex differences in science lies in the development of occupational interest, as it has been suggested females are encouraged away from science due to stereotypes and social pressure. The present study evaluates high school juniors and seniors (n = 295) to explore their preference for science as indicated by science motivation, attitude, academic experience, and interest. Latent Profile Analysis was used to model profiles of preferences for science with a person-centered approach. Then, the impact of self-concept variables was explored and four profiles of science interest were identified. Sex differences were identified based on science interest, but were not always in favor of males. Covariate analysis indicates vocabulary ability and personality as significantly different for students in the high science interest profile. Implications of these results and future research directions are discussed.

Social deficits are one of the defining symptoms of autism spectrum disorder and affect a child’s ability to build relationships with others. These deficits put children with autism at a disadvantage when most of their world is focused on building connections with others – family, friendships, and community ties. Sunny Starts, a service-learning project, was created to specifically meet the needs of families with young toddlers with autism. The primary focus of Sunny Starts is to enhance the quality of the parent-child relationship by teaching parents a basic teaching interaction and to arrange the child’s environment in ways that are mutually reinforcing. The purpose of this experiment is to study the effects of the Sunny Starts DANCE training package, a responsive parent training program, on three levels of parent and child behaviors: 1) teaching episodes, 2) turn taking, social attending, vocal requests, and 3) synchronous engagement. Participants included two parent-child dyads. Parent training included 5-minute video assessments, video review, descriptions, rationales, modeling, practice, and feedback. The effects of the parent training were evaluated using a concurrent multiple baseline across participants. Results indicate parent teaching episodes and child behaviors (turn taking, social attending, and verbal requests) increased during the intervention phase. …

An evaluation of a series of interventions was conducted for an individual who engaged in life-threatening rumination and emesis. There is substantial research indicating that the delivery of peanut butter (Barton & Barton, 1985; Greene, Johnston, Rossi, Racal, Winston, & Barron, 1991) and/or chopped bread following meals (Thibadeau, Blew, Reedy, & Luiselli, 1999), chewing gum (Rhine & Tarbox, 2009), and satiation procedures (Dudley, Johnston, & Barnes, 2002; Lyons, Rue, Luiselli, & DiGennario, 2007; Rast, Johnston, Drum, & Conrin, 1981) can be effective treatments for rumination. In the current case, each of these interventions was found to be either ineffective or contraindicated based on the participant's fragile health status. Previous literature has shown that liquid delivery can affect rates of rumination in some clients (Barton & Barton, 1985,; Heering, Wilder, & Ladd, 2003). We examined how liquid affected the rate of rumination during and after meals. Based on the individual's medical condition, oral nutrition and fluids were discontinued indefinitely and a gastronomy-jejunostomy tube was used for nutrition. All rumination ceased when fluids and nutrition were delivered via the jejunostomy tube. Finally, a fluid analysis procedure was implemented in which the participant received small amounts of fluid while NPO. Color and flavor …
